IMPROVEMENT IN sKATEs.

Specification forming part of Letters Patent N 0. 155,015, datedSeptembcr15, 1874; application filed June 19, 1874.

To all whom t may concern:

Be it known that I, REGINALD H. EARLE, of St. J ohns, in Newfoundland,have invented a new, and useful Improvement in of which the following isa specification:

Figure l is a bottom view of one of my improved skates, part of theblade being broken away to show the construction. Fig. 2 is a side viewof the same. Fig. 3 is a detail crosssection of the same taken throughthe line .fr w, Fig. l. y

My inventionV has for its object to furnish improved skates, which shallbe so constructed 4that they may be readily and quickly attached to anddetached from the boots without the use of a key or wrench, which willbe held securely, and may be readily adjusted to the The inventionconsists in the combination of the adjustable arms, the slotted plates,the pin-blocks, and the slotted sliding plate with the foot-plate andthe skate-blade; in the combination of the movable heelplate and itsarm, and the swiveled screw with the stationary heel-plate, theskate-blade, and the movable plate; and in the combination of thepivoted bent lever with the foot-plate and with the movable plate andits attachments, as hereinafter fully described.

A represents the blade or ru'ner of the skate, to the upper edge of theforward part of which is secured a plate, B, upon which the forward partof the skaters foot rests. To the upper edge of the rear partof theblade A is attached a plate, C, the forward part of which is turnedupward, or has an upwardlyprojecting ange formed upon it, upon the up--per edge of which are formed rearwardly-projccting prongs c, to enterthe front edge of the boot-heel. Upon the under side of the foot-plate Bis formed a transverse dovetailed or T groove, in the middle part ofwhich are placed two small blocks, D, one upon each side of the blade A,and to which are attached pins d', which pass through holes in the innerends of the small plates E. In the outer parts of the 'transversegroove` in the plate B are placed two sliding arms, F, the outer ends ofwhich are bent upward, and are corrugated to clasp the side edges of theboot-sole. The

outer parts of the plates E rest upon the in- Iier parts of the arms F,and are slotted 1ongitudinally to receive the screws G, which passthrough the said slots, and screw into the said arms F, to connect thesaid arms F adjustably with the pin-blocks D. This construction allowsthe arms F to be readily adjusted to the width of the boot-sole, towhich the skate is to be attached. H is a narrow plate, interposedbetween the blade A and the foot-plate B, and which has shortlongitudinal slots formed in its forward part, to receive the studs bywhich said blade A and plate B are secured to each other. In the sideparts of the forward end of the plate H are formed inclined slots, toreceive the pins d', so that the arms F may be drawn inward to clasp theboot-sole, and pushed outwardvto release said sole by the longitudinalmovement of the plate H. rIhe rear end of the plate H is bent downwardat right angles, and has a screw, I, swiveled to it, which screw isprovided with a small hand-wheel, and passes through a screw-hole in theturned-down forward end of the arm J formed upon or attached to theplate K, which rests upon the plate C, and is connected with it byscrews or rivets, which pass through 1ongitudinal slots in the saidplate C. The rear end of the plate K is turned upward, or hasupwardly-projecting lugs or flanges formed upon or attached to it, andcorrugated or roughened to clasp the rear side of the boot-heel, andpress it against the prongs or teeth of the plate C. By thisconstruction, by turning the screw I, the skate may be readily adjustedto t boot heels of different sizes. L is a bent lever, which is pivotedat its angle to the rear part of the plate B, and the end of its shortarm is pivoted to the plate H, so that by moving the lever L the arms Fwill be drawn inward, and the plate K will be drawn forward to clasp theboot sole and heel, securing the skate firmly. The skate is released bymov- .ingl the lever L in the opposite direction.

The lever L is so arranged that it may be parallel with, and close to,the side of the bladeA when the skate is secured tothc boot, where it issecured in place by a catch attached to the stationary heel-plate C.

Having thus described my invention, I claim movable plate H, allconstructed and arranged as new and desire to secure by LettersPatent- 1. The combination of the adjustable arms F, the slotted platesE, the pin-blocks D, and the slotted plate H with the foot-plate B andthe blade A, substantially as herein shown and described.

2. The combination of the movable heelplate K, arm J, and swiveled screwI With the stationary heel-plate C, the blade A, and the substantiallyasherein shown and described.

3. The combination of the pivoted bent lever L with the foot-plate B andwith the movable plate H and itsattachments, constructed and arranged tooperate as herein shown and described.
